Changes:
o build fix: cygwin has no sys/shm.h and sys/ipc.h, so configure
disables all targets requiring them, if not present.
o cbconsist demo: sync with devel tree
o gcc 3.3 compiling fix for default/linear_16/crossbuild.c
(fixes Debian bug #197214)
o merged build fix from FreeBSD's ports tree to make the xf86dga
target compile on FreeBSD (fixes FreeBSD PR ports/52380)
o X-target
+ minor mode initialization fix from Argo Vessmann
+ shm helper checks return code, when setting up the
directbuffer
+ release locking on failure. (Threadsafety fix)
+ fixed geometry check. Opening (very) small windows is now
possible.
